Announcement: Introducing HL8545/G: Quad-Channel 50 mΩ High-Side Switch for Advanced Automotive Applications


The HL5097 is a high-performance USB Type-C connector protection IC including two channels for CC or SBU interface. Two input pins (IN_SIG1 and IN_SIG2) of HL5097 facing USB connector have 28V maximum voltage rating to be protected from overvoltage by shorting these signals with VBUS voltage up to 20V. 

Downstream system can be protected safely from overvoltage condition, ESD and surge by using HL5097 OVP switch. IN_SIG1 and IN_SIG2 OVP thresholds are pre-fixed to 5.8V for HL5097WL01 and 4.8V for HL5097WL02.  

For more detailed description of the device, please download a product brief.
